NAME

       XkbGetControls - Finds the current state of Xkb server controls

SYNOPSIS

       Status XkbGetControls (Display *display, unsigned long which, XkbDescPtr xkb);

ARGUMENTS

       - display
              connection to X server

       - which
              mask of controls requested

       - xkb  keyboard description for controls information

DESCRIPTION

       XkbGetControls  queries  the  server  for  the  requested control information, waits for a
       reply, and then copies the server's values for the requested information  into  the  ctrls
       structure  of the xkb argument. Only those components specified by the which parameter are
       copied. Valid values for which are any combination of the masks listed  in  Table  1  that
       have "ok" in the which column.

       Table  1  shows the actual values for the individual mask bits used to select controls for
       modification and to enable and disable the control. Note that the same mask bit is used to
       specify general modifications to the parameters used to configure the control (which), and
       to enable and disable the control (enabled_ctrls). The anomalies in Table 1  (no  "ok"  in
       column)  are  for controls that have no configurable attributes; and for controls that are
       not boolean controls and therefore cannot be enabled or disabled.

       If xkb->ctrls is NULL, XkbGetControls allocates and initializes it  before  obtaining  the
       values  specified by which.  If xkb->ctrls is not NULL, XkbGetControls modifies only those
       portions of xkb->ctrls corresponding to the values specified by which.

       XkbGetControls returns Success if successful; otherwise, it returns BadAlloc if it  cannot
       obtain   sufficient   storage,   BadMatch   if   xkb   is  NULL  or  which  is  empty,  or
       BadImplementation.

       To free the ctrls member of a keyboard description, use XkbFreeControls.

       The num_groups field in the  ctrls  structure  is  always  filled  in  by  XkbGetControls,
       regardless of which bits are selected by which.

RETURN VALUES

       Success        The XkbGetControls function returns Success if successful.

DIAGNOSTICS

       BadAlloc       Unable to allocate storage

       BadImplementation
                      Invalid reply from server

       BadMatch       A  compatible version of Xkb was not available in the server or an argument
                      has correct type and range, but is otherwise invalid
